Bug #: 56131
Summary: [4.8 regression] gcc.dg/pr56035.c ICEs gcc on
sparc-linux
Classification: Unclassified
Product: gcc
Version: 4.7.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: regression
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mi...@it.uu.se
The recently added gcc.dg/pr56035.c test case fails on sparc-linux:
+FAIL: gcc.dg/pr56035.c (internal compiler error)
+FAIL: gcc.dg/pr56035.c (test for excess errors)
Compiling it with an x86_64-linux to sparc-linux cross-compiler shows:
> /tmp/objdir/gcc/xgcc -B/tmp/objdir/gcc/ -O1 -ftree-vectorize
> -fcse-follow-jumps -fstrict-overflow -S pr56035.c
pr56035.c: In function 'f':
pr56035.c:35:1: internal compiler error: Segmentation fault

This ICE is different from the one in PR56035.
Reverting the PR56035 fix in r195462 makes no difference.
gcc-4.7 does not ICE on this test case.
